Many of the default ANSI colors used by the CygWin terminal are almost unreadable. For example, the blue that is used for directories in a file listing is pretty dark and hard to read on a black background. This limits the color palette that can be used in things such as the PS1 shell prompt. Try the following script (colortable16.sh) to see what your colors currently look like.

The colors can be changed by clicking on the system menu in the upper-left corner and selecting “Properties”. I decided to use the same colors as the Gnome terminal.

This is how the colors are defined in CygWin by default:

This is how they should be changed so that they’re more usable:

This is a very simple script. See the usage at the top of the script starting on line 28.

Checks for particular id3v2 frames in a set of files.
Usage:
    $0 <option> <FRAME> files...

Options:
    -m | --missing  Show files that are missing the frame
    -h | --has      Show files that have the frame
    -s | --show     Show the contents of the frame
    -a | --all      Show all the frames

For example, to find mp3's with no album art:
    $0 -m APIC *.mp3

Some sample frames:
    APIC    - Cover art
    TIT2    - Song name

In case it might be useful to others, here’s a script that can be used to convert a bunch of *.wav files to *.flac and *.flac files to *.mp3. The script will first first convert all *.wav files (if any) to *.flac, then it will convert all *.flac files to *.mp3. See the usage instructions starting on line 31 below for more details.

I called the script

Usage:
$0 source/dir dest/dir

All wav/flac files in source/dir and its subdirectories will be converted to
mp3 and placed in dest/dir while maintaining the directory structures. ID3
tags will also be copied from flac to mp3 files.

Existing files (mp3 or flac) will not be overwritten.
Source and destination directories can be the same.

Both cygwin and the msysgit shell will use the same ~/.bashrc file on start-up, but they mount the local Windows drives at different mount points. Cygwin uses /cygdrive/c while msysgit uses simply /c so if you’re using ~/.bashrc to configure various settings that have to do with drive letters in your bash shell, you’ll need to distinguish between cygwin and msysgit.

The easiest way to do this is to look for the presence of /etc/bash.bashrc in ~/.bashrc, since this file is typically only present in cygwin. If by any chance it’s present in both cygwin and msysgit, a variable can be set in just one of them and ~/.bashrc can be configured to source /etc/bash.bashrc and test for the presence of that variable.

if [ -e /etc/bash.bashrc ] ; then
